TED talk on menopause and the brain

@eat well and exercise is apparenlty the answer to everything.  If that was actually true all the good people that do those things would never get cancer right? We know that's not true.  The last thing I read about soy was they were looking into to the ages of people.  e.g over use of soy in infant formula and pre puberty females was looking not so flash for BC.  Synthetic versions added to foods etc not so good either vs the naturally occuring stuff.  I got bored reading as the study was very long and contradictory depending on where the information came from. Plus it was 10 yrs old. 
I haven't been able to find anything recent, but then again I've stopped looking as it's all just too confusing. This is it if you have time to slog through it.
